Replaced 4wd switch on dashboard, did not solve problem. 4wd doesn't connect.


Which of these transfer case's does your truck have ?
Transfer Case - NVG 149-NP3 Transfer Case - NVG 246-NP8 Transfer Case - NVG 261-NP2 Transfer Case - NVG 263-NP1
The NVG 263 transfer case features a three button shift control switch located on the instrument panel.
DTC B0790 DTC B2725 DTC C0306 DTC C0327 DTC C0359 DTC C0379 DTC C0550

The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel.
DTC B0790 DTC B2725 DTC C0300 DTC C0305 DTC C0306 DTC C0321 DTC C0327 DTC C0359 DTC C0374 DTC C0379 DTC C0550
Regardless both of these switch's are input's to a control module . There are probably DTC'S - diagnostic trouble codes stored . You should have the vehicle checked for DTC , That means taking you vehicle to the repair shop .

Have a 2004 gmc yukon getting codes c0040, c0550,c0455,c0296 in the abs computer. Trac and abs light on as well as suspension control.


C0040 - Right Front Wheel Speed Circuit Malfunction
C0550 - ECU Malfunction - internal write / checksum malfunction
C0455 - Either:
  • A bent terminal or poor connection at the SWPS may be one possible cause; or
  • The vehicle stability enhancement system (VSES) electronic brake control module (EBCM) calibration may be the other possible cause.
C0296 - Transfer Case Delivered Torque for Stability Control System Circuit

What is the part number for the Transfer Case Control Module on a 2003 Chevy Tracker?


12590219 or 12590220 are the part numbers. GM has issued a technical bulletin that most failures are caused by bad connections rather than defective control module. If code c0550 is present in module or the scanner can't communicate with module are the only reason to replace the control module.

What would make my service abs system,service brake system,service traction system,service stability system come on with the ecu/ccu malfunction code c0550


You have to realize that your wheel speed sensor is what tells all of these systems what each wheel is doing, I would think one of these would be the problem, but without putting it on a computer you can't know which one.

2-04-21-006E: Inoperative 4WD/AWD Lamps, Inoperative 4WD/AWD System, DTC C0550 Set No Communication with TCCM (Reprogram Transfer Case Control Module) - (Jul 20, 2006)
999999995.gif Subject: Inoperative 4WD/AWD Lamps, Inoperative 4WD/AWD System, DTC C0550 Set, No Communication with TCCM (Reprogram Transfer Case Control Module) Models: 2004 Buick Rainier 2002-2004 Chevrolet TrailBlazer, TrailBlazer EXT 2003-2004 Chevrolet Avalanche, Silverado, Suburban, Tahoe 2002-2004 GMC Envoy, Envoy XL 2003-2004 GMC Sierra, Yukon, Yukon XL 2004 GMC Envoy XUV 2002-2004 Oldsmobile Bravada with Electronic Shift or Active Transfer Case (RPOs NP1, NP4 or NP8)

This bulletin is being revised to add Subject information and change the labor operation. This bulletin cancels and supersedes Bulletin Number 03-04-21-006. Please discard Corporate Bulletin Numbers 02-04-21-006D and 03-04-21-006 (Section 04 -- Driveline/Axle).
ConditionSome customers may comment that the 4WD/AWD indicator lights on the selector switch do not work, or the 4WD/AWD system may be inoperative and/or the service 4WD light is illuminated. The condition is typically intermittent and always occurs at key-up. Upon investigation, the technician may find DTC C0550 set.
CauseThe Transfer Case Control Module (TCCM) has not received the wake-up call during key-up and has remained in the "sleep mode".
When the TCCM is in the "sleep mode", it will not communicate with the class II bus or the Tech 2®.
Correction
  1. Try to communicate with the TCCM. If no communication, go to step 2. If communication is possible, go to step 5.
  2. Remove the underhood (ATCM or TREC) TCCM fuse.
  3. Wait 30 seconds.
  4. Reinstall the fuse. The module should "wake up" and communicate with the Tech 2®.
  5. Check for codes in the TCCM. If a C0550 is found current or in history with or without other codes, replace the module and go to step 6.
  6. Reprogram the TCCM with the latest TIS software using normal SPS procedures.
  7. Verify operation and that no codes are present.
Important: For the 2002 model year, the TCCM must be replaced and reprogrammed.

My brother's sprayed engine cleaner on my 2003 Yukon XL and then washed it off with a water hose. 30 minutes later while driving my ABS plue Parking Brake lights came on with a message saying Check Brake...


C0550 is the code for the ABS module. It is on the frame under the vehicle around the drivers door area. It is a module with all the brake lines coming from it. Reset the trouble codes and see if the problem returns. If it does, the module is not serviceable and will need to be replaced.
